  • Where possible the wording "Reproduced with permission of the International Union of Crystallography" should be included. In electronic form, this acknowledgement must be visible at the same time as the reused materials, and must be linked to the original article using its DOI.

Please use the button below if you require a permissions certificate for a particular article.
